Be it known that I, JASPER FRED KOBLER, a citizen of the United States, residing at N iagara Falls, in the county of Niagara and State of New York, have invented a new and useful Capsule-Filling Machine, of which the following is a specification.

his invention relates more rovided with a series of particularly to means for introducing material into capsules. transverse grooves 1n which are seated a plu- The principal object is to provide novel rality of tubes 22, said tubes projecting mechanism of a simple nature whereby mathrough and beyond the side walls 2. One

series of projecting ends constitute capsuleholding nipples and are spaced a suilioient distance apart to allow of a capsule, as 20, being placed u on each. The other projecting portions o the tubes that extend from the opposite side of the casing constitute inlet ends, the terminals being referably cut away, as shown in Figs. 2 an(i)4. The ortions of the tubes that are located within the chamber D haveltheir upper halves out away, so that the bores of said tubes have communication with the interior of the chamber, and the capsule-holding nipples thus have communicating terial can be equally and properly divided into doses or portions and placed in capsules or like holders, said mechanism being very j convenient to use and eliminating the tedious operation of filling capsules by hand with its variable results.

embodiment of the invention that is at present considered the preferable one is illustrated in the accompanying drawings, where- 1n` Figure 1 is a Side elevation oi the apparatus. Fig. 2 is a vertical cross-sectional view therethrough on the line A A of Fig. 1. Fig.

The open-sided portions an end elevation ofthe machine. Fig. 5 is a of the tubes located within the chamber constitute pockets or channels for the reception of the material. The bottom or under side of the pressing-plunger 6 has corresponding pockets or channels 29, which coperate with those formed by the tubes, so that when the plunger is in place within the chamber the bottom thereof will complete the channels and form completed bores equal in diameter to the bores of the tubes. f

yIn connection with the above-described mechanism means are employed for forming a preliminary cake of the material to be divided within the chamber D. In the present embodiment this means consists of a slide 18, that comprises a partition or false bottom which removably passes through a slot 17 in one end of the chamber and is movable over the tops ofthe pockets or channels. A ressblock 23 is arranged to iit within the chamber D and is employed when the slide 18 is in place therein. A leveling-gage 25 is also employed, thev same being formed of slidablyassociated sections which are adapted to be held in adjusted relation by a thumb-nut 27. One ofthe sections the side walls 2, while the other is provided with outstanding lugs 28, that ride upon the upper edges of said side walls.

view similar to Fig. 3, but showing the press opened and a cake of material formed therein. Fig. 6 is a horizontal sectional view on the lines C O of Fig. 5. Fig. 7 illustrates the evener in side and edge elevation.

Similar reference characters designate oorresponding parts in all the iigures of the drawings.

n the embodiment illustrated a base comprising sections 1 are provided with upstanding parallel side walls 2, having upper eXtensions at their upper corners in the form of ears 3. A bottom 4, located between the lower portions of the side walls 2, is provided with upwardly-extending portions disposed between the sides. These various elements are secured together by bolts 5 passing through the side walls 2 and the bottom and end member. As a result a chamber D is formed, which, as shown in Fig. 6, is oblong.

A pressing-plunger 6 is movable in the chamber D and has an upstanding stem 7, which is screw-threaded. This stem has a threaded engagement with the iianged hub 8 of a hand-wheel, said hand-wheel comprising spokes 9 and a rim 10. The hub Sis jourv naled in a yoke comprising a collar 13, having opposite outwardl -eXtending arms 14, one of said arms being pivoted to one of the sets is arranged to fit between Brieiiy described, the structure is em- IIO by sliding the two sections upon each other and securing them, as will be understood by reference to Fig. 7. After the material has been properly smoothed the press-block 23 is placed thereupon and a preliminary compacting of the material is made thereby.

cake is thus Jformed, which is shown in Fig. 5 and is'designated 24. The slide 18 and pressblock 23 are then removed and the yoke, with its pressing-plun er, is swung over the chamber, said yoke being secured. It will thus be apparent that if the hand-wheel 1() is rotated l in the proper direction the pressing-plunger 6 will be forced downward and the cake divided into sections or doses which are cylindrical in form and of a proper diameter to pass freely through the discharge-nipples. An expellinglunger 21 is then employed which is passed into the inlet ends of the tubes 22 and across the chamber, thereby expelling the material through the nipples into the capsules and in turn expelling the capsules from the nipples.

It will thus be seen that an exceedingly simple structure is rovided whereby material may be equally divided with ease and expedition and easily placed in capsules or other holders, thereby eliminating the tedious manual Jfilling operation now ordinarily employed.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacriicing any of the advantages of the invention.
